TO ALL WHOM IT MAY CONCERN:-

Be it knownthat I, WILLIAM JONES, of Chelsea, in the county oi'Sulfolk, andQ-Statebt Massachusetts, have invented an Improvement in `BurningGns for Heating; and I dohereby declarethat-thefollowing, taken in v connection with the drawings which accompany and form part of this specification-fis 'ade'scription'of my inventtienfs'uicient to enable those skilled in the 'art to practisei 'jj 1 It has long been known'that the mixture of atmospheric air and common street-gas, which will burn with blue dame, is a'convenient means for heating, and it is to the detail by which such mixtureis made and applied thatmy invention rclates. 3'

' My invention consists,vfirst, in a peeuliarconstruction of gas-eock, within which the mixture is made, and from and through which it is supplied to the point where the combustion takes place; and, second, in an arrange- -ment of parts by which, in coniined spaces,'like calender-rolls, for example,.pure atmospheric air is obtained for mixing with the gas, instead of vitiated air, such as exists within the calender-roll-where.the flame is burning. The ordinary way of mixing' air and gas to be burnedfor the purpose of producing heat instead ol' light, is to cause the air to enter the pipe-conveying the gas near the point where the mixture is consumed.

Inheating calendering-eylinders in the common way, with apertures in the` pipe between the gas-cock and the end of the pipe at which the mixture is burned, said apertures' receiving air 'from within' the calenderng` cylinder for mixing with the' gas, it 'has always happened that shortly after starting the flame, and as soon as the air in the cylinder becomes vitiated, the flame will smoke and coat the-interior of the cylinder, thus impairin'g its eicieney and increasing the consumption of the gas. I

This dibliculty I have remedied' by placing 'not only the gas-cock outside ofthe Vheated chamber, but the z tpierturevthrough which the gas is supplied with the air which is to be intermixed'therewith.

In the ordinary mixing-apparatus, the atmospheric air is made to ilow in jets Iinto-a pipe 4filled with gas. I obtain .improved results for admitting the gas in ne jets into arpipe'or chamber, through which a current of atmospheric-air passes, and where the pipe conveying themixture of air and gas is horizontal, or nearly so, I` make the opening through which the air enters to mingle with the gas, at-such 'adistance below the inlet of the gas and the outlet of the mixture, thatneither the gas nor mixture will escape at the air-inlet, the gas and themixture being bothlighter than the air, are, as it were, sealed from escapeby the incoming curren't'of air.v

The drawing-shows, in sectionalelevation, tin-apparatus embodying bo'th parts 'of my invention.

i a denotes a calendering-rollor cylinder, mounted so as to turnon a hollowpivot, b, in the' bearing c. Through the hollow pivot or journal, the pipe d passes,rha'ving its end turnedinpward, toward the materiale? the roll which is to be heatedby combustion of a mixture of gasand air at the open endof said pipe.`

Outside of the bearing is'aplug-cock, of peculiar construction, theprpose of the cock being to admitboth c ir and gas, and to-cause them to mingle before passing into the pipe ol. e isthe'plugof the cock, working in the barrelf, y being the end of the cock to which the gas-conveying pipe is iixed, while ,the other end, h, of the cock, is ixed to the pipe ol, conveying the mixture of air and gas. y

The plug e is hollow, with an opening at the lower end thereof, and the chamber e' in the plug is made to communicate, by a large opening, j, with the pipe oZ, and with the gas-pipe, by several minute holes, lc k.

The gas flows into the chamber z', in fine streams, through 7c c,hin the direction indicated by thcarrows, and' mingles with the atmospheric air present inlthe chamber z', and, asthe` mixture, which is `lighter than'the air, moves in the pipe d to supply the ame, the atmospheric air moves lup the Chamb-cr z', as indicated bythe arrow on the drawing. I i l As in any cock, a slight turn of the plug shuts o' the supply of gas when the llame at the end of d is to be extinguished. I l, I

I claim, for the purpose of mixing air and gasto be'burned, a plug-cochhaving along, open, chambered plug, with inlets c c and outletj, .arrangedte operate substantially as described.

Also, in connection with a burner, arranged withina confined space, provision substantially as shown and described, for supplying fresh unvitiated atmospheric air, to be mingled with the gas passing to the flame, as
